At BellVue Gems, we believe an informed customer makes confident decisions. Let’s demystify the 4Cs of diamonds – Cut, Color, Clarity, and Carat Weight – to help you choose the perfect stone for your special moment.
Cut: The Most Important C
Cut is the factor that most influences a diamond’s sparkle and brilliance. Unlike what many think, cut doesn’t refer to the shape (round, princess, etc.) but rather how well the diamond’s facets interact with light.
Cut Grades:
- Excellent: Maximum brilliance and fire
- Very Good: Nearly optimal light reflection
- Good: Good brilliance, value-oriented choice
- Fair/Poor: Noticeably less sparkle
What makes a great cut:
- Optimal angles and proportions
- Symmetrical facets
- High-quality polish
- Proper depth and table percentages
Color: The Less, The Better
Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). The less color, the more valuable the diamond.
Color Scale Breakdown:
- D-F: Colorless (highest value)
- G-J: Near colorless (excellent value)
- K-M: Faint color (visible tint)
- N-Z: Very light to light color
Tips for color selection:
- Color becomes more noticeable in larger diamonds
- Yellow gold settings can make lower color grades appear whiter
- Platinum or white gold settings look best with higher color grades
- Most BellVue Gems customers choose G-J for the best value
Clarity: Nature’s Fingerprint
Clarity refers to the presence of inclusions (internal) and blemishes (external). Nearly all diamonds have these natural characteristics.
Clarity Scale:
- FL/IF: Flawless/Internally Flawless
- VVS1/VVS2: Very, Very Slightly Included
- VS1/VS2: Very Slightly Included
- SI1/SI2: Slightly Included
- I1/I2/I3: Included
What to know about clarity:
- Most inclusions aren’t visible to the naked eye
- VS2-SI1 often provides the best value
- The importance of clarity varies by diamond shape
- Some inclusions can impact durability
Carat Weight: Size Matters, But…
Carat refers to the diamond’s weight, not its size. One carat equals 0.2 grams.
Carat Weight Tips:
- Look for slightly under whole carat weights for value
- Consider surface area over carat weight
- Remember that shape affects perceived size
- Higher quality can make a diamond appear larger
